The mapping isn't available in the e-mail itself (presumably it is
available on http://gmane.org somewhere).  I proposed that gmane.org
should add some headers that map newsgroup back to the list address
for this purpose, and Gnus could add a specific gmane.org-hack to
recognize that header.  Not very elegant, though.

I suppose this is a general issue with mail2news gateways and
hashcash.  Has there been any discussions for how to handle it?

Only according to RFC 822, but not according to RFC 2822.
